Research On Distribution Network Planning Of Wuhai City

As a link between the city and the power grid,the distribution network plays an extremely important role in the development of the city.With the continuous development of the city,the old distribution network can not provide the city with a matching power supply.Therefore,with the continuous increase of urban load and the increasing demand for power quality,the structure and equipment of the distribution network need to be constantly adjusted and upgraded.Therefore,it is an important issue to rationally plan the distribution network and continuously upgrade the grid structure of the distribution network so as to ensure the economical efficiency and reliability of electricity consumption in cities.This work intends to carry out research on the current situation,the status of economic and social development,and the status quo of distribution networks in Wuhai,and draws the main problems in the distribution network of Wuhai City;through the data mining and analysis of Wuhai City's electricity consumption data,the total electricity load growth trend and load characteristics in the region were summarized,and the influencing factors affecting regional electricity demand were analyzed in depth,based on this,five mathematical models were used to forecast the electricity consumption and maximum load in Wuhai City,and the spatial load of Wuhai City was forecasted using the method of residential load density index.After clarifying the general principles and planning objectives,combined with the current situation of distribution network in Wuhai City,the technical principles for distribution network planning in Wuhai City were proposed;based on the Wuhai electric power load forecasting and distribution network planning principles,the demand for main transformer capacity in each region was analyzed and calculated,and plans for 110 kV,35kV,and 10 kV substations in Wuhai were formulated.The medium and low-voltage distribution network planning plans for the four central urban areas,five industrial parks,Beihai New Area,and rural power grids were studied;finally,the investment estimate for the distribution network planning of Wuhai City was calculated.This study is conducive to the promotion of regional distribution network planning method in-depth study,and provides scientific basis and data reference for Wuhai City distribution network planning and design.
